摘要： A method and apparatus for non-contact measurement of the viscosity of a liquid such as paint. In accordance with the method and apparatus, the surface of a liquid is perturbed with a standing wave of predetermined wavelength. This perturbation is effected by directing a burst of air against the surface of the liquid using periodically spaced air nozzles. The frequency and rate of decay of the induced surface wave is measured using typically optical means including a reflected light beam. The measured frequency and decay rate are combined with the known depth of the liquid sample in a computing circuit to provide a measurement of fluid viscosity.

摘要： An electrical circuit component is temporarily fixed to a temporary substrate. Electrical contacts on the component are interconnected with corresponding contacts on the test substrate by lead wires or ribbons using a bonding wedge that forms the lead wires into a gull-wing shape with central portions thereof formed adjacent to edge portions of the component. The component is subjected to a test procedure while fixed to the temporary substrate via signals applied to the contacts thereof. The lead wires are then severed near their connection to the temporary substrate, and the component with the remaining lead wire portions attached is removed from the test substrate. The lead wires are sufficiently stiff and/or are adhered to the edge portions of the component with an adhesive so as retain their shapes after removal of the component from the temporary substrate. The component is then adhered to a permanent device substrate, and the ends of the lead wires are bonded to corresponding contacts on the device substrate.

摘要： An electrical circuit pattern (52) is formed on a glass-ceramic, thermally fusible tape (50). The tape is heated to a temperature at which it becomes temporarily plastic, and is then bent into a desired non-planar shape. Further application of heat causes the tape to be sintered in the non-planar shape. A multi-layer structure can be provided by laminating plural layers of Low-Temperature-Cofired-Ceramic (LTCC) tape (10, 12, 14) with respective circuit patterns (10a, 12a, 14a) formed thereon together, and plastically bending the laminated structure into the non-planar shape during the heating step. A circuit struture including an edge connector (50b) can be formed by laminating a layer of glass-ceramic transfer tape having an electrical circuit pattern which includes conductor strips (52c) formed on an edge connector portion thereof onto a relatively rigid substrate (54), such that the edge connector portion is bent around an edge of the substrate to form a rigid edge connector. The edge connector portion of the transfer tape which is formed into a non-planar shape during the lamination step, is fused together with the remaining portion of the transfer tape onto the substrate during the heating step.

摘要： A system and process for metering the delivery of liquids (from reservoirs 14, 16, and 18) to apply the liquids to an object, such as an automobile (10). The conductivity of the liquids is monitored at a metering device, such as a spray gun (50) by means of a conductivity cell (54). Measurement of conductivity at the metering device provides continual measurement for fluctuations in conductivity and is useful for controlling liquid flow during sequential metering of different liquids.

摘要： An infrared (IR) simulator is disclosed in which an array of pixels is defined on an insulative substrate by resistor bridges which contact the substrate at spaced locations and are separated from the substrate, and thereby thermally insulated therefrom, between the contact locations. Semiconductor drive circuits on the substrate enable desired current flows through the resistor bridges in response to input control signals, thereby establishing the appropriate IR radiation from each of the pixels. The drive circuits and also at least some of the electrical lead lines are preferably located under the resistor bridges. A thermal reflector below each bridge shields the drive circuit and reflects radiation to enhance the IR output. The drive circuits employ sample and hold circuits which produce a substantially flicker-free operation, whith the resistor bridges being impedance matched with their respective drive circuits. The resistor bridges may be formed by coating insulative base bridges with a resistive layer having the desired properties, and overcoating the resistive layers with a thermally emissive material. The array is preferably formed on a silicon-on-saphire (SOS) wafer. Arrays of electromagnetic radiation bridge detectors may also be formed, with the bridges having either resistor, thermocouple or Schottky junction constructions.

摘要： A stereo image enhancement system, in which difference signal components in relatively quieter difference signal frequency bands are boosted to provide an improved stereo image, is provided with a stereo input that is synthetically derived from a monaural signal (L + R). Simulated sum (L + R)s and simulated difference (L - R)s signals are provided from a monaural input (L + R) by sending the input through a phase shifter and splitter (12) that provides 0° and 90° outputs with a constant 90° phase separation between the two at all audio frequencies. The leading one of the two output signals from the phase shifter is employed as a simulated sum signal, and the other as a simulated difference signal. The simulated difference signal has different frequency components, each delayed by different amounts relative to corresponding components of like frequency of the simulated sum signal. This provides an effective synthetic difference signal, with both sum and difference signals being suitably filtered to provide an improved pair of synthetically derived stereo sum and difference signals (L + R)s, (L - R)s as inputs to an image enhancement circuit.

摘要： An optical neural network stores optical transmission weightings as angularly and spatially distributed gratings within a phase conjugate mirror (PCM) (38), the PCM (38) using a stimulated process to generate a phase conjugated return beam without separate external pump mechanisms. An error signal is generated in response to differences between the actual and a desired output optical pattern, and is used to adjust the PCM gratings toward the desired output. One or more intermediate image planes may be employed along with the input and output planes. The input and intermediate planes, as well as the error signal, are preferably displayed on the surface of a spatial light modulator (28). The output optical signal is transduced into an electrical format for training the neural network, with the error signal also generated electrically. A significant increase in neuron and interconnection capacity is realized, without cross-talk between neurons, compared to prior optical neural networks.

摘要： A low temperature cofired monolithic ceramic package (10) for use with microwave and millimeter wave gallium arsenide integrated circuits, or the like. In situ buried passive components (22), including capacitors, resistors, couplers and inductors are incorporated within a cofired substrate structure (12). Fields of interconnected staggered or stacked vias (56, 58) are provided in the substrate below the integrated circuit for efficient heat transfer and electrical connection to a ground plane (20) that eliminates complicated heat sink structures. At least one cavity (24) is provided in the top surface to confine integrated circuit chips (28). A plurality of connectable electrical conductors (34, 36, 38, 40, 42) including RF input and output leads and DC bias leads for the chip extend from the edge of the substrate (12) to the edge of the cavity (24). A sidewall (14) is extended around the periphery of the cavity (24) and comprises a low temperature cofired structure which is cofired with the substrate (12). The sidewall (14) has a metallized top surface and interconnected metallization and vias extending from the top surface to the top surface layer of the substrate (12). A cover (16) is provided which is attachable to the metallized top surface of the sidewall (14). The electrical and thermal interconnections provided in the sidewall (14) and substrate (12) are provided by means of the plurality of interconnected staggered or stacked via interconnects. Electrical and thermal integrity is achieved which permits dissipation of heat by way of the ground plane and top cover, and electrical shielding is achieved by interconnecting the conductive components.
